The Chequered Flag (The Saint TV Series)

Plot
Oscar Newley has perfected a new fuel injection system for his racing car and approaches the Saint for financial backing. However the car breaks down during a race and he believes that it has been sabotaged by Ellington, a rival owner-driver. Suspicions are compounded when Oscar is nearly killed in a fire at his work-shop and the car is again sabotaged. The chief culprit would seem to be Oscar's driver Alec but then he is murdered. The Saint must race to find the perpetrator in every sense.

Trivia

 * The reason Tempar's standard Volvo P1800 isn't seen is simply because he's he's undercover as he investigates, and pretends to be someone else (his typical alias, 'Simon Toombs'), and doesn't wish to give any hints of his actual identity.
 * The character Justine Lord plays here - someone close to, but not involved with the main suspect, primarily interested in Simon Templar (going so far as to getting into his private room/residence), and supporting him upon his arrival - is almost identical to the one she had just played in her previous appearance in the series, The Saint Steps In.

Miscellaneous

 * At about 28 minutes, the track side advertising words are reversed.

Origin
This episode was adapted from the short story "The Newdick Helicopter" from the 1934 book Boodle.
